()这样的代码 friend std::ostream& operator<<(std::ostream& os, const Student& stu); public: std::string m_id;//学号 std::string m_name;//姓名 int m_age;//年龄 std::string m_date;//生日 }; std::ostream & operator<<(std::ostream & os, const Student & stu) { //向os输出...
第17行使用member function的方式overload + operator,18行使用global function的方式overload * operator,這兩種寫法都可以,惟若使用global function,由於要存取data menber,所以要宣告該function為friend,這樣才能存取data member。 19行我們overload了<< operator,由於也是global function,所以也要宣告friend。 最後49行...

Output streams use the insertion (<<) operator for standard types. You can also overload the << operator for your own classes. Example The write function example showed the use of a Date structure. A date is an ideal candidate for a C++ class in which the data members (month, day, ...
(原創) 如何使用Operator Overloading? (C/C++) 2007-01-18 01:46 − Operator Overloading讓我們可以自己定義Operator的功能,讓程式可以更精簡,C#也有,不過不是很強調,但C++非常強調Operator Overloading,這是C++的一大特色。... 真OO无双 1 56873 相关推荐 (...
public static yyy operator + ( yyy x , yyy y) { System.Console.WriteLine(“operator + “ + x.i + ““ + y.i); yyy z = new yyy(x.i+y.i); return z; } } Output Operator + 10 5 Operator + 15 2 17 The only change is d = a + b + c. C# gets easily confused with ...

Cents operator+(const Cents& c1, int value) { // use the Cents constructor and operator+(int, int) // we can access m_cents directly because this is a friend function return Cents { c1.m_cents + value }; } // note: this function is not a member function! Cents operator+(int ...
The return types are limited by the expressions in which the operator is expected to be used: for example, assignment operators return by reference to make it possible to write a = b = c = d, because the built-in operators allow that. ...
